Inshore Fishing - ScotMap (2013) - Number of Crew

ScotMap is a Marine Scotland project which provides spatial information on the fishing activity of Scottish registered commercial fishing vessels under 15 m in overall length. The data were collected during face-to-face interview with individual vessel owners and operators and relate to fishing activity for the period 2007 to 2011. The data are aggregated and analysed to provide information on the monetary value, relative importance (relative value) and the usage (number of fishing vessels and crew) of seas around Scotland.

The dataset, as of July 2013, is based on interviews of 1,090 fishermen. Individuals defined their fishing areas or 'polygons' with variable levels of precision. Users of the data should be aware of this, particularly of the coverage provided by the ScotMap data set which varies regionally.

This layer shows the number of crew associated with each grid cell. The average number of crew working on a vessel is attributed to each polygon for that vessel. The same value is then allocated to each overlapping grid cell and numbers summed to derive the number of crew associated with each grid cell.
